I don't work for Hsu Research nor have any affiliation with them but after reading the rave reviews about Hsu's subs I took a dive and ordered an STF sub. I encountered some problems with my sound but everything worked out in the end after I talked to their technical support line.

I left a message in the evening and received a call back within the hour. I normally don't give rave reviews but I have to say their customer support is top notch. Thanks to Hsu Research and the sub sounds amazing.

I bought the STF-2 for Christmas last year and have loved it to death for nearly 365 days!!! As with you, the customer support was top notch and the sub sounds amazing! Very musical subs!

Dr. Hsu knows what he's doing. I've been enjoying his sub for years.
